I have white Corelle, and have for years. But, if you use a dishwasher, and it has rusty areas on the racks, and you're too lazy to coat them, and not willing to do something, like reroof the house, for your husbasnd so HE can coat them, the edges of the plates get a rusty mark on them. Oh, and if you're too lazy to scrub the rust off (will it even come off?) it makes a polkadotted edge stack in the cupboard
